Application filed October 9, 1902. Serial No. 176,611. (No model.)

improve the construction of window-operat ing mechanisms and to provide simple and comparatively inexpensive gearing of great strength and durability adapted to be readily applied to a Window and capable of operating pivoted, slidable, and other movable sashes. The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is an elevation of a window provided with operating mech- 2 5 anism constructed in accordance with this invention and showing the same applied toa pivoted sash. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view of one side of the window. Fig. 4 is an enlarged detail sectional view illustrating the manner of mounting the gearing on the squared chair. Fig. 5 is an elevation of a window, showing the operating mechanism applied to vertically movable sashes. 5 Fig. 6 is a vertical sectional view of the same. Fig. 7 is a sectional view on the line 7 7 of Fig. 6. Fig. Sis an enlarged detail view of the gear-wheel and the opposite rack-bars.

Like numerals of reference designate cor-' 4o responding partsin all the figures of the drawings.

1 l designate suitable bearing brackets mounted on a window-frame 2 at opposite sides thereof and provided with circular open- 5 ings for the reception of bearing-sleeves 3 of a transverse shaft 4, which is square, as clearly illustrated in Fig. 2 of the drawings, but which may be of anyother polygonal form. The sleeve 3, which may be secured to the shaft in any suitable manner, has its open- .be employed, if desired.

ing conforming to the configuration of the same, and it may be retained in the bearingopening of the bracket 1 by any suitable means, such as a set-screw and an annular groove or the like. I

Mounted on the squared shaft are gearwheels 5, located at opposite sides of the window and meshing with rack-bars 6, which are connected with a pivoted sash 7 and which are adapted to be reciprocated by the gearwheels to swing the sash for opening and closing the window. The sash is provided at opposite sides with suitable brackets 8, having perforated ears arranged in'pairs and receiving the adjacent ends of the rack-bars, which are connected with the ears by suitable pivots 9. Each gear-wheel is provided with opposite hub extensions 10 and 11, and it has a squared opening to conform to the configuration of the shaft 4. The hub extension 10 is squared or rectangular in cross-section and receives a disk or collar 12, secured to the polygonal extension 10 by any suitable means and projecting outward beyond the teeth of the gear-wheel to hold the adjacent rack-bar 7 5 against lateral movement to prevent the same from becoming displaced. The other hub extension ll of the gear-wheel is cylindrical to receive a guide-arm 13, provided at its inner end with an eye 14 and having a pivot 15 at its outer end. The eye of theguide has a threaded perforation for the reception of a set-screw 16, which passes one side of the eye and extends inward through the same for engaging an annular groove 17 of the cylindrical hub extension of the gearwheel. An antifriction-rolleror gear-wheel 18 is mounted on the pivot 15 for engaging the smooth upper face of the rack-bar, which is provided at its lower face with teeth, and

a disk or washer 19 is secured to the outer end of the pivot to form a projecting flange for engagingthe adjacent side face of the rack-bar; but a grooved wheel or roller may The gear-wheels 5 are readily adjusted longitudinally of the squared transverse shaft, and it is unnecessary to perforate'the gear-wheels or socket or perforate the shaft for fixing the gearwheels to the shaft, and the construction is able means,and the gearing (shown in Fig. 1) l much stronger 'than those devices in which the gearingis secured to the shaft by a clamping screw or key.

The shaft is operated by a short shaft 20, arranged at right angles to the transverse shaft and mounted in a bracket 21, consisting of an approximately rectangular portion 22 and L-shaped arms 23. The L-shaped arms 23 are provided with bearing-openings to receive a sleeve 24 and a hub extension 25 of the gear-wheel 26, the sleeve and the gearwheel being provided with square openings to conform to the configuration of the transverse shaft. The rectangular portion 22 is provided with bearing-openings for the reception of a sleeve 27 and a hub extension 28 ot' a pinion 29, which meshes with the gearwheel 26. The gear-wheel 26 is provided at one of its faces with teeth to mesh with the teeth of the pinion. arranged at its outer side, as shown in Fig. l. The gear-wheel is provided at the inner portion of its hub extension with a shoulder for engaging the inner face of the adjacent arm of the bearing-bracket 21, and the pinion is also provided with a similar shoulder for engaging the inner end of the rectangular portion of the bearing-bracket, the outer end of the rectangular portion of the bracket being engaged by a shoulder of the sleeve. The short operating-shaft may be rotated by the operation of a crank or any other suitmay be mounted at any other desired point for operating the pivoted sash or a similar pivoted element.

In Fig. 5 of the drawings is illustrated an operating device for simultaneously raising and lowering upper and lower sashes 30 and 31, provided with upper and lower arms 32 and 33, formed integral with plates or brackets and arranged in pairs, as shown in Figs. 5 and 6. The outer ends of the arms of the brackets are connected by suitable fastening devices with upper and lower rack-bars 34 and 35, located at opposite sides of gearwheels 36 and adapted to be reciprocated when the same are rotated. The gear-wheels are mounted on a squared transverse shaft 37 and are provided with hub extensions 38 and 39, constructed similar to those before described. The hub extension 38 is squared to receive a disk or collar 40, and the other hub extension 39 is cylindrical to receive an eye 41 of a guide 42, which is provided with oppositely-disposed arms having pivots at their outer'ends. The eye has a threaded perforation to receive a set-screw 43, which engages an annular groove 44 of the hub extension. The pivots 45 at the outer ends of the arms receive antifriction rollers or wheels 46 for engaging the rack-bars to retain the same in mesh with the gear-wheels. The pivots are also provided with disks or Washers 47 for engaging the adjacent side faces of the rack-bars.

The pinion has its teeth The transverse shaft is journaled in suitable bearings of brackets 48 by means of sleeves 49, having squared openings to receive the shaft and arranged in circular openings of the bearing-brackets. The sleeves 49 may be retained in the openings of the bearing-brackets by means of set-screws, annular grooves, or any other suitable means. When the transverse shaft is rotated, the

rack-bars will be reciprocated and the upper.

and lower sashes will be simultaneously raised and lowered. Any suitable means may be provided for rotating the transverse shaft.

It will be seenthat the window-operating device is exceedingly simple and inexpensive in construction, that it possesses great strength and durability, and that it is adapted to be readily applied to a window.
